Free Landscaping Calculator – Sod, Seed & Gravel
Calculate sod rolls, seed bags, or cubic yards of gravel and topsoil for any landscaping project with optional cost estimation.
Landscaping Calculator Guide
The Landscaping Calculator estimates material quantities for sod, grass seed, gravel, and topsoil projects. Enter your area dimensions and select the material type to get accurate estimates including waste factor.
Standard sod rolls cover 9 square feet each (2ft x 4.5ft). For grass seed, coverage varies by type — check the bag label. For gravel and topsoil, depth is the key variable: 3 inches is standard for ground cover, 4-6 inches for walkways.
Always apply at least a 10% waste factor. Sod needs trimming at edges, seed may wash away or fail to germinate, and volumetric materials settle 10-20% after installation. Order from the same batch for consistent appearance.
